A method for handling logs, wherein the method comprises the following steps: retrieving or generating a unique code at a first moment; establishing, by means of a position determining device, position information as to the geographical position of a portable, hand-held log marking tool (1) at said first moment; applying the code as a corresponding code marking on a log by means of the log marking tool at a second moment and automatically establishing a time value representing the time elapsed between said first moment and said second moment; comparing said time value with a predetermined time threshold value; andstoring the code as an authenticated code in a database associated to the position information when said time value is smaller than the time threshold value. The invention also relates to a log marking tool (1) for use in such a method.

A method and system for planting seedlings including a seedling handling system, a seedling chute system and a planting head. The method includes retrieving a row of seedlings and then delivering the row of seedlings to the planting head for individual planting of the seedlings.

A spreading device, a powder-like mixture composition and a method for spreading the composition for control or prevent forest pathogens on tree stumps are disclosed.

The first embodiment of the tool for girdling the trunk of a tree includes an elongated and horizontally disposed handle having first and second ends. The tool also includes a horizontally disposed cutting blade support having a first elongated arm portion and a curved arm portion. The first elongated arm portion is pivotally connected to the handle intermediate the lengths thereof. A linkage also pivotally connects the second end of the handle to the first end of the first elongated arm portion. A cutting blade carriage is selectively movably secured to the curved arm portion to compensate for various tree trunk diameters. A second embodiment of the tool includes an elongated handle which is adjustably secured to a cutting blade support which has a cutting blade secured thereto which is forced into engagement with the tree trunk by a spring arm.

A device for holding a wood log in place in such a way that a person can cut the log with a saw or split it with an axe is disclosed. The device can be attached to trees or vehicles to keep it in place and can be assembled and disassembled with relative ease. The device is configured to hold the logs between two support arms attached to a post and a grip member attached to each of the support arms. The post is configured for attaching to standing trees through extending arms or brackets and configured for position adjustments by way of sliding inside sleeves that attach to the post, bracket or a hitch of a vehicle.
